At least one station, the Quick Stop on Portage Road in Kalamazoo, has raised its price to $3.89 by this morning, according to www.gasbuddy.com. On that web site, there is also a report that a station in Sturgis has gone up to $3.99, but it hasn't been confirmed.

Gasbuddy issued an alert on Wednesday that area prices could go up to as high as $3.99, starting today. That rise hasn't started yet, though, so there is still time to fill up before the price heads closer to $4.

The lowest price in Southwest Michigan is $3.61 at a Citgo station on U.S. 12 in Sturgis. There are also quite a few stations in Sturgis, Battle Creek and Marshall which are at $3.69.

The lowest price in Kalamazoo and Portage is $3.70 at the Admiral, Meijer and two Speedway stations in the South Westnedge Avenue corridor.
